Say you have 27 small cubes. you put them together and make a big cube. meaning you have 3 layer of 9. now you painted all the faces of the big cube. how many cubes are not painted.

a.0
b.1
c.4
d.7

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

a - base

b - exponent

so,
